15 Claims.

This invention relates to certain new and, useful improvements ingaltake-out device, more particularly a device, adapted to receive, support and transport to anew position finished glass articles as delivered from a glass-working machinev of the-rotary turret type. It will, however,-

,; be apparent. as the disclosure proceeds that this take-out device is adapted for use. with other machines or. other articles than those herein 'disclosedby wayof example. g Y In a glass-working machine of the type with ,[which this take-out deviceis especially designed (to cooperate. the glass articles, when completed,

, are suspended byupper neck portions from glass- .w'orking spindles which move continuously with the machine through a" circular path, of travel.

' V ,by the spindles they drop onto achute or deflector l whichdirects,th. onto aconveyor or into a [receiver, or the articles may be individually" graspedbysuitable' 'tongsbefore they are released and then carried away. The present takeout device relates to an improved .means for When these'flnished glaas articles are released ,7 receiving and disposih cf these completed glass ,articl es. Briefly described, this, device comprises j a continuously moving looped conveyor which is mounted adjacent the glass working machine and is bodily movable toward and from the machine so that article-carriers mounted on the conveyor .may be moved'into engagement with the glass articles before they arereleased by 7 pp ing spindle. Whenso positioned, efadiacent run of the conveyor moves syn onously with the articles as carried by the machine. when "the articles are released by the spindles. they are supported by the carrier-sand the conveyor moves away from the machine and the article carriers 'move to a location at which the glass articles are'removed from the conveyor or otherwise disp doff. j The principal object of this inventionis to prowvide an improved take-out device of the type briefly described hereinabove and disclosed more in 'detailin the specifications which follow.

Another object is to provide a take-out device that'is driven from the glass-working machine and adapted to move, at times, in 'synchronism 7 I "therewith.v

vAnother object is to provide a take-out device embodying article-carriers or. receivers that may i travel vertically with the glass] articles when re-g m leased by thespindles.

I Another object is to provide improved means 9 for adjusting and supporting the conveyor-chains and thearticie-carriers supported thereby,

' Other objects andadvantages of this invention will be more apparent from the following detailed description of one approved form of apparatusv constructed and operating according to theprinciples of this invention.

At the right of Fig. l is shown a portion of a glass-working machine of well known type, this machine comprising a turret structure indicated generally at A which rotates rather slowly (in a clockwise direction, as seen from above in this figure) about a central verical axis, which would be located considerably to the right of the sheet. Spaced at equal intervals about the periphery of this turret are glass-working heads 13, each comprising a pairof similar spindles C. Ina machine'of the type here shown by way of example there are twelve heads 13 and twenty-four spindles C. It will be understood that each spindle C performs a similar operation and there are two spindles on each head, merely for the and clamped in place by the jaws c and c. As the head B moves around through its continuous path of travel, the spindles and the glass blanks carried thereby are inverted so that the blanks hang downwardly. The spindles are rotated and air is forced through the spindles into the blanks so that the'blanks are expanded to form, first in -theopenaiirandthenwithinmoldsl3whichare "moved into position about the glass blanks or suspended thereby are lowered somewhatinciparisons. After the glass blanks are blown to final shape, the molds D are opened and withdrawn to the position shown inl 'ig. 2, and the finished glass articles a: are then suspended by spindles C which still grip an upper neck portion of the article. The spindles and glass articles suspended therefrom have now reached the posttion shown in Fig. 1. Shortly thereafter the spindle jaws c and c are separated to release the- 7 glass article a. Due to construction of, the spindles C, the jaws c and c' and the articles eration is aptto break or deform the articles.

The improved take-out device which forms the particular subject matter of this invention is adapted to grasp the articles before they are released from-the glass-working spindles C and then carry these articles to a position away fromthe machine where they are finally disposed of.

The improved takeeout device comprises asupporting frame I which is fixedly mounted, as indi-.

cated for example at 2, on some portion of the fixed supporting frame of the glass-working machine. A tubular supporting bracket '3 mounted on-the outer portion of frame I carries the roller bearings 4 and 5 in which is mounted the vertically extending tubular member 6 of a swinging frame, which frame also comprises the horizontally extending beam 1 secured to the upper end portion of tubular member C, and the diagonal supporting member I which is secured at its upper end to an outer portion of beam I and at its lower end to the lower end portion of tubular member 6. The lower end portion of member 8 extends through a slot or opening 9 in the supporting frame I. A vertical drive shaft In is mounted for rotation inframe member 6 about the vertical axis of swinging movement of the frame. Shaft II is driven through bevel gears II and I2 from the outer end:of a horizontal shaft I2 journaled in frame I. A second short vertical shaft II is journaled in bearings I5 and- It in a tubular bracket I! mounted on frame I. The lower end of shaft is driven through bevel gears "and I. from the horizontal shaft I3.

The upper end of shaft It carries a cam 20. A

downwardly sloping arm 2i is secured at its upper end to the tubular member '6 of the swinging frame, and carries at its lower end aroiler 22 positioned to bear againstthe cam 20. A spring 23 connected between arm 2i and a portion of the fixed supporting frame I tends to constantly swing the arm 2| and the swinging frame in such a direction as to hold roller 22 against the cam 2|. When roller 22 is engaged by the high portion 24 of cam 20, the swinging frame and the conveyor mechanism carried thereby (as hereinafter described) will be swung away from the glass- .working machine. When roller 22 moves onto the low portion II ofcam the spring 23 will] swing the framev and conveyor mechanism toward the glass-working machine. I f

Thehorizontal shaft ii is driven through bevel gears 20 and 21 from a short vertical shaft 28 journaled in the hub portion 2! of a supporting .plate II adjustably mounted on the frame I. A

spur gear 2| secured on the upper end of shaft 2| is driven, through idler gear 32,-fromthe largo annular gear 13: mounted on the rotary turret A of theglass-working machine. It will now be apparent that when the glass-working machine is in operation. the drive shaft II and cam 2| of the take-out mechanism will be driven in synchrotherewith, through the chain of gearing .hereinabovedescribed.

The idler gear 32 is mounted for rotation on the supporting plate 3|. Boits 33 which extend through slots 24 in plate Iii adjustably secure this plate in position on the fixed frame I. By loosening the bolts 33 and swinging'plate II to one side, the idler 82 maybe moved out ofmesh with gear E so as to-permit the glass-working machine to rotate without driving the take-out mechanism.

A pair of similar sprockets I! and II are mounted on a hub 38 which is secured on'the upper end portionof drive shaft It. A supportinl block 31, (see Figs.'3 and 4) is slidable in guideways I! inthe forked outer end portion SI of beam 1. The block 21 may be adjusted toward or away from the axisof drive shaft II by means of screw ll threaded in a cross member ll of beam 1 and locked in place by nut 42. A short vertical stub-shaft ll mounted in block Il'extends upwardly and'a hub rotatable on this'shaft by means of bearings and 46 supports a pair of sprocket wheels '41 and I1 which'are similar to f the driving sprockets II and 3! already described. The traveling conveyor mechanism comprises a sprocket chain 48 looped about the upper pair of sprockets. 3i and 41, and a'similar chain ll looped about the other pair of sprockets SI and 41'. These chains ll and 40 are tied together at spaced intervals by the vertically extending plates 4! which support the article carriers; In the present example there are three of these article carrying units spaced at equal distances throughout the length of the chain loops, and indicated at so, II and '52 respectively in Fig. 2. It willbe understood that the number of these article carrying units will vary in accordance with the length of the conveyor, these units being so spaced apart as to cooperate successively with the differcut pairs of spindles C of the glass-working ma- 7 chine as these spindlessuccessively revolve into position adjacent the take out mechanism.

A roller ills mountedonthe pivot pin 54 secured in the lower end portion' 55 of each support ing plate 49, this roller traveling on a looped track ll positioned beneath the conveyor chain. This supporting roller prevents. sagging of the chains and supports the greater part of the 'weight of the article carrier and the load supported thereby. The two side runs and one looped end of the trackway 5B are permanently supported from the frame beam i'by means of the outwardly projecting side arms 51 (Fig. 3) but the outerend loop 58 of the trackway is supported by an arm 59 projecting from the adjustable block 31, already described, and guided in the cross bar 00 secured to the ends of the'yoke arms 3!. The

end portions of the track loop- 58 have lapped joints 8| and 82 with the respective ends ofthe side runsof the trackway. It willnow be seen that by adjusting the position'of the block 31, the end sprockets l1 and 41 may be moved to tighten or adjust the conveyor chains 48 and ll and at i'romapairofspindlescxlj 4 I f Apost' l: h i ns-upward ri m a P w rth; 'supportingtrame I'pivotally carries the mascot length or the trackway. willbeadiustedto oithechainsr, V v Eacharticle carryingunit compiisesasupportsupportingplatellsnd projects upwardlya conisiderahle; distance vabove the .plate and conveyor nl w h a vertically slide-way l4, and in the upper portion with a slot ll-ex- The carriage has a rearwardly'proiecting, boss which extendsythroughslot ll and carries a roller II; A forwardly proiectin'giarmi Cl at theupperthroughowhich' projects the threaded rod ll adsupport. the carriage and the :Iiedthereby from thexrod IL A horizontally expel-J1 is can-led by the lower end 11 7 ,39-0! theqcan-iage, thi's'barsupporting ateach end Jone c'tithe-yokedarticle-simporting members inflmembersflcomprisesapalr or similar sldearms ll ,eachprovided vwith'a angled extension I 1;at itsrearend, theseportions It being overlapped placeably secured on the outerends of theyoke fingers II c! the yoke-are adapted to bit projected cles a: (suspended oi the frame.
